ZIBA G. WARD, OF ESTES, TEXAS.

MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Apr. 15, 1913.

Application filed July 18, 1912. Serial No. 710,213.

To all whom it may concern:

Be it known that I, ZIBA G. WARD, a citizen of the United States,residing at Estes, in the county of Aransas and State of Texas, haveinvented certain new and useful Improvements in Mechanical Movements, ofwhich the following is a specification.

This invention relates to mechanical movements and pertains especiallyto improved mechanism applicable to windmills for operating pump-rodsand the like..

The object of the invention is to provide certain devices andcombinations thereof for automatically reciprocating a pump-rod or thelike during the revolution of the Wind- 'wheel shaft.

A further object of the invention is to provide novel and peculiar meansfor automaticallyoperating a shaft-clutch and reciprocating a pump-rodduring the operation of the windmill.

In the accompanying drawings forming part of this application Figure 1is a side elevation, partly in section, showing my windmill in liftingoperation. Fig. 2- is an end view, with the wheel removed, showing themovement of the brake band in dotted lines. Fig. 3- is a sectional viewon the dotted line 00.0c Fig. 1. Fig. 4- is a perspective view of theclutch, the yoke and the reciprocating stem.

The same reference characters denote the same parts throughout theseveral views of the drawings.

The shaft 1 of the wind wheel 2, is journaled in end uprights 3 and 4 ofa frame 5, having the top end of a tube, cylinder or casing 6, attachedthereto for a reciprocating rod 7. The shaft 1 has one member 8 of a.

clutch secured thereto, and the other clutch member 9 is formed on oneend of a drum or Windlass 10 slidable on the shaft, and the other end ofthe drum 10 has an annular groove 11, for a yoke 12, hereinafter moreparticularly referred to. The shaft 1 has a brake-pulley 13 attachedthereto upon the outer side of the upright 3, and the short curved arm14, of the vane 15 is pivoted to the top of the upright 3, and the longarm 16 of the vane is pivoted at the bottom of said upright so as tolimit one movement of the vane. A brake-band 17 has its ends attached tothe arms 14 and 16 adjacent the upright 3, and said band is curved orbowed into such shape as to engage the pulley 13 accordlimit themovement of the vane in the other direction.

The device or mechanism for automatically reciprocating the rod 7 andsliding the drum, comprises the said yoke 12 which is pivoted at 18 toeach side of the frame 5, and has inward projections 19 fitting theyoke-groove 11, an arm 20 projecting from one side of the yoke above thecasing 6, and having an elongation or slot 21 central with the top ofthe casing, a stem 22 projecting from the rod 7 through the slot 21, andprovided with stops 23 for limiting the movement of the stem, and achain or cable 24 having one end attached to the drum 10. A hand chainor rope 25, may be attached to the rod 7 or to the stem 22 for fixingthe rod 7 or to assist in starting the operation of the reciprocatingrod.

It Will be seen that the stops are adjustable on the stem so as tochange the stroke of the reciprocating rod as desired or as occasion maydemand.

In operation; during the revolution of the shaft 1, and while the drumis clutched wit-h the shaft, the drum-chain or cable raises the rod 7until the stop on the lower portion of the stem 22 strikes or engagesthe under side of the arm 20, which engagement automatically slides thedrum out of clutched position with the shaft and permits the rod to dropuntil the stop on the upper portion of the stem 22 engages the upperside of the arm 20, and such engagement automatically slides the druminto clutch engagement with the shaft.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is 1. The combination with a supporting framehaving uprights at the ends thereof, a shaft journaled in the uprights,and a reciprocating lift rod, of a drum slidable on the shaft, a clutchbetween the shaft and the drum, a stem having stops and projecting fromthe said rod, a cable attached to the rod and windable on the drum, anda yoke pivoted to the frame and engaging the drum and having said stemextending therethrough for operating the clutch.

2. The combination with a supporting frame, a shaft journaled in andextending through the ends of the frame, and a lift rod, of a drumslidably and revolubly mountthe clutch, and a chain or cable attached to10 ed on the shaft, a clutch for coupling the the rod and windable onthe drum.
